Whered you hear Wildstar is going to open beta soonish? It's currently in CB2 with a potential stress test weekend coming up. But there will be a CB3 and probably CB4 long before an open beta. I don't expect an open beta before fall.
Don't try to level, don't try to sell anything. They HAVE to do a rollback, the economy and zen exchange are too screwed up for bans alone to be sufficient. Plus probably half the playerbase have profited from this so they would have to ban too many people.
